• Destination-hash distribution based on the destination address only. IP

forwards all packets with a given destination address to the same next hop.

If you enable equal-cost multipath support on the router, IP can store multiple

equal-cost best RIP and OSPF routes in the routing table. When RIP or OSPF

submits a route to a destination, one of the following events occurs:

• IP determines that the current route to that destination is better than the new

route. IP discards the new route.

• IP determines that the new route is better than the current route. IP discards

the current route and replaces it with the new route. If the routing table

contains multiple equal-cost best routes, IP discards all of these routes.

• IP determines that the new route and the current route have the same cost. IP

adds the new route to the routing table -- up to a maximum number that you

specify. If the routing table already contains the maximum number of

equal-cost routes from RIP or OSPF, IP discards the route.

By default, equal-cost multipath support is disabled on the router. If you enable

equal-cost multipath support on the router, you must set the maximum number of

equal-cost routes (up to five) that IP stores in the routing table for RIP and OSPF.

Using the BCC

To enable or disable equal-cost multipath support, navigate to the IP global

prompt (for example,

box; ip) and enter:

ecmp-method

method

is one of the following:

disabled (default)

roundRobin

srcDestHash

destinationHash

To specify the maximum number of equal-cost paths for RIP, navigate to the IP

global prompt (for example,

box; ip) and enter:

rip-max-paths

<max_number>

max_number

is an integer from 1 (the default) through 5.
